Şayet sınav gözetmeni gecikirse uygulamalı sınavı erteleyeceğiz.

Şayet means if. It is correct and natural, but it sounds somewhat formal or written. In everyday conversation, eğer or just the conditional suffix by itself is more common.

For example, all of these can work:

• Şayet sınav gözetmeni gecikirse...
• Eğer sınav gözetmeni gecikirse...
• Sınav gözetmeni gecikirse...

They all express the same basic idea.

This is a common Turkish noun-compound pattern. Sınav gözetmeni means exam invigilator / exam proctor and is built like this:

• sınav = exam
• gözetmen-i = invigilator + compound suffix

In Turkish, the second noun in this kind of compound usually takes -(s)I. So the -i in gözetmeni is part of the compound itself.

Because that -i is not the accusative ending here. It is the compound marker.

The whole phrase sınav gözetmeni is the subject of gecikirse. Turkish subjects usually have no special nominative ending, so they often look unmarked.

A useful comparison:

• sınav gözetmeni = the exam invigilator / proctor
• sınav gözetmenini = the exam invigilator / proctor as a definite object

So in your sentence, gözetmeni is still part of the subject phrase.

It comes from gecikmek, meaning to be late or to be delayed.

A helpful breakdown is:

• gecik- = verb stem
• -ir = aorist/general marker
• -se = conditional if

So gecikirse means if he/she/it is late or if he/she/it gets delayed. This kind of form is very common in Turkish for real future conditions.

Turkish often leaves pronouns out when they are clear from context. Here the subject is already given as sınav gözetmeni, so there is no need to add o.

English often needs a pronoun, but Turkish usually does not.

In this sentence, it naturally covers a future possibility. Turkish does not need a separate word like will in the if-clause.

So gecikirse can be understood as:

• if the invigilator is late
• if the invigilator ends up being late

Both match the Turkish form well.

Uygulamalı means practical, applied, or hands-on, depending on context. In uygulamalı sınav, it refers to a practical exam rather than a purely written or theoretical one.

It is related to uygulama, meaning application or practice, and the ending -lı / -li often gives a sense like with or involving.

Here -ı is the accusative ending, marking a definite or specific direct object. The thing being postponed is the practical exam, a specific exam known in the situation.

So:

• uygulamalı sınav = a practical exam
• uygulamalı sınavı = the practical exam, as the object of the verb

This is different from gözetmeni, where the -i belongs to the noun compound.

It comes from ertelemek, meaning to postpone.

You can break it down like this:

• ertele- = postpone
• -y- = buffer consonant
• -ecek = future marker
• -iz = we

So erteleyeceğiz means we will postpone.

The y appears because the verb stem ends in a vowel and the future suffix begins with a vowel. Turkish often inserts a buffer consonant in that situation.

Turkish normally puts the verb at the end, and it often places a condition clause before the main clause.

So the structure is:

• Şayet sınav gözetmeni gecikirse = if the exam invigilator is late
• uygulamalı sınavı erteleyeceğiz = we will postpone the practical exam

This order is very natural in Turkish. Some parts can move for emphasis, but the main verb erteleyeceğiz will usually stay at or near the end.

Yes, but şayet makes it sound a bit more formal or written. In casual speech, many speakers would probably say:

• Sınav gözetmeni gecikirse uygulamalı sınavı erteleyeceğiz.
• Eğer sınav gözetmeni gecikirse uygulamalı sınavı erteleyeceğiz.

So the sentence is fully natural, but şayet gives it a slightly more formal tone.
